- To all whom it may concern:

Be it known that I, JOHN W. SUTTON, a citizen of the United States, residing at Collinsville, Cherokee Nation, Indian Territory, have invented a new and useful Vehicle- ,Y Spring, of which the following is a speciiieation.

, which will appear as the nature of the invention is better understood, the saine' consists in certain novel features of construction, as hereinafter fully described and claimed.

In the accompanying drawings, forming a part of this specification, an in which corresponding parts are denoted b like designating characters, is illustrate the referred form of embodiment of the invent-lon capable of carrying the same into practical operation, it being understood that the invention is not necessarily limited thereto, as various changes in the shape, proportions, and generalassembla'ge of the arts may be resorted to without departing om the principle of the invention or sacrificing any Yof its advantafres.

lln the drawings thus employed, Figure 1 is a plan view of the runnin r-gear of a vehii cle with the improvements applied. F iv. 2 is a rear elevation of the rear axle, toget er with the spring-bolster and lspringxconstruction and other attachmenth. F1 Bis an enlarged detail of the improved cip device, whereb the body portion of the vehicle is couple to the running-gear. Fig; 4 is an enlarged perspective view of the jolt-relievin spring detached. F ig. is an enlarge sidyiew of portions of the springsupporting mechanism. Fig. 6 is an end elevation of the parts shown in Fig. 2 -enlarged and with the axle in section on the line 6 6 of' said figure.

The improved device may be ai plied to any of the various constructions o vehicles manufactured, but is more particularly applicable to carriages, buggies, and similar vehicles, and for the `purpose of illustration is shown applied to a conventional construction of running-Gear and body of an ordinary vehicle of this ciaracter, 10 11 representing the axles, 12 the reach, 13 the forwardr springbolster, and 14 the rear sprin bolster The reach portion of t e device will preferably be widely extended for connection to the rear axle to increasev the stability, and generally the iifth-wheel upon the forward axle will be larger than usua for the saine reason.

The improved springs are formed in coil shape, as at 15, preferably conical, and com nected between the rear axle 11 and the rear .of the body portion and between the forward bolster 13 and the forward portion of the body, the means whereby the coupling is accomplished being part of the no vel ieatures of the present invention and which will now.

bc described. 'i

Attached to the bolster members 13 and 14 near the ends are plates 16, the latter havm ing spaced ribs 1'! for bea 0' over the bol ster members and connected t iereto by clipm bolts 18 and clamp-plates 19, the bolts hav ing hooks u on the u per ends for engaging the lower w -rls of t e coiled springe. By this means the plates and lower ends of the springs are both secured firmly in position by' t e same clip-boite.

Connected to the body portion of the vchi ele, both at front and rear, are beams 20, one only boing shown, the coupling being 'made `by clip-bars 22, bolted, as at 23, to the/under side, of the body portion (indicated at 21) and embracing the beams 20 and bolted thereto, as at 24.

Attached, respectively, to the axles 1() .l1 are relieisprings for absorbing the jars or concussione to which the springs are liable, and thus effectually prevent undue vibra tions or lateral movements to thebody: portion, while at the same time' permitting e. requisite amount of lateral and longitudinali movement. The relief-springs consist of spaced coils 25 26, each connected by an integral bar 27, fitting in a transverse cavity in the under sides of the bolsters 13 14 and with their free ends extended and terminating;l in loops 28 29 to receive straps 30, the latter passing upward `through apertures in the lili? LFI.

checked and the jars and concussions very' largely absorbed and prevented from being unduly imparted to the body of the vehicle.

The holsters 1 3 1 4 are connected' lto their respective axles by clips 32, and between the' holsters and axles at the points where the clips are applied spring-plates 33 are disposed, the spring-plates extended laterally and projected toward the center ot the axles and provided at their inner terminals with rollers Se, the rollers being thus spaced apart a short distance centrally of the running-gear. rihe holsters and axles, together with the springplates, are further streiigtlr-'i ffd and supported by clamp-bolts 35.

The cavities for the trm; members 2?' of the relief-springs through the bolsters next to the swing-plates 33 and are held in position thereby when the axles and holsters are clann'ied togetl'ier,

Attached centrally olf tho beams 20 are plates 36, dart-shaped at their lov/'er ci'ids and with spaced recesses if?? in their sides, for engagement 'with the rollers when tl i body portion of the vehicle is dopre 'ed below the normal, as when subjected to a sudden jolt when suddenly engaging;` an obstruction er rough places in the road. rlhc lengths of the plates 36 will be so proportioned relative to the location of the rollers vl-'ll-hat the plates will not engage the rollers so long' as the vohicle is operating under normal ci'inditions; .but in event of any abnormal depression of the body portion and springs caused by sudden contact with an obstruction or in riding' rapidly over rough roads or from other cause the dart-shaped'plates 36 will come in contact with the rollers and the downward movement resisted thereby and undue vertical movement thereby prevented. ll' the downward movement is sulliciently strong', the spring-plates will be depressed sutlicien tly to permit the rollers to pass into the recesses 37 and be thus checked in the return or upward movement, and undue jolt/ingr action ellectu'ally prevented. lly this simple moans the unpleasant and annoying' tendency of the body portion to rebound violently when one or morelof the wheels moet an obstruction or drop into a rut or other cai/ity is counter-` aetjcd rndthe jolting; force absorbed by the spring members 38. This portion ol' the device is ot' especial value and advantage when employed upon top buggies or carriages, as the unpleasant and annoyingtendency of the tops to swayyor Whip about when thi` 26 pass siae're above-described jolts are produced is obviated, and no danger therefore exists of injury or annoyance to the occupants of the vehicles from that source. Another advantage of this construction is that in event ofthe draftanirnals suddenly jumping'` forward or suddenly stopping the limited degree of longi- 7o tudinal movement permitted to the spring structure willA ellectually prevent this action from producing' any unpleasant or harmful eilect upon the occupants of the vehicle, and the same is true in. event oi" any sudden lateral 7 5 movement which may be imparted to the running-gear from any cause.

It will thus be noted that a simply-constructed and durable spring' structure is prof duced which may be installed upon any of 8o the various forms ot buggies and carriages manufactured and may also be easily adapted for the heavier class oi' vehicles, if required, and'while permittingr a requisite degree of both lateral and longitudinal swaying or vi- 85,w b 'ation in addition to the usual vertical movement 'will eil'ectually check and retard all undue 'niovement, and also ellectually prevent unpleasant rebounding movements from jolts or abnormal movements imparted 9o to the running-gear The strengtboi the springs 'l5 being' :much `greater than the strength ol' the springs 83, the latter will yield alter the 'toreo ol the .rebound is exhausted, and thus permit the members 36 to 95 'be gradually iif'itlidrawn troni engagement with the rollers 34 and without producing any unpleasant el'l'ects upon the occupants of the vehicle.
